IBM Tivoli NetView for z/OS Programming: Pipes - IBM notice

Examples
any VET command with a PF or PA action key. Instead of specifying a PF or PA
key, place the required command in /string/ and use ENTER for the action key.
For example, code NETVIEW VET /RETURN/ ENTER instead of VET PF3.
v After a VOST terminates, the NetView program retains the last data transmitted
by the application that was running on the VOST for up to 5 minutes. A VET
NEXT obtains this data as though the application was still active. After the last
transmitted data has been obtained by VET, an additional VET NEXT obtains no
data and a VET CURRENT returns a blank screen.
v VTAM commands are not supported on a VOST. The MVS command must be
used to issue VTAM commands on a VOST.
v The line count attribute is set in BNH150I for VET ROWS output. This line count
value can only be used by the EDIT pipe stage.
The BNH150I label line has LINECOUNT=0 and all other lines are numbered 1
through 24 corresponding to their line number on the virtual screen. An example
use for the line count data is in determining the line where certain data was
found. This can be done in pipeline processing using LOCATE and the line
count.
Example: Request Current Screen
The following VET stage specification requests the current view of the application
panel running on the VOST named MYVOST. The screen data is to be returned in
ROWS format.
PIPE VET CURRENT ROWS NAME MYVOST | ...
Example: Writing Data to a VOST
This example writes FORWARD to the command line, which in the application
running on VOST MYVOST is found at row 24 column 8. The default action key
ENTER is assumed.
VET 24.8 /FORWARD/ NAME MYVOST
Example: Writing Multiple Lines to a VOST
Null values for /string/ can be used to tab through fields. The following example
shows a stem variable containing five values. The first four are null and the fifth
contains an X. The following REXX fragment places nothing in the first four
unprotected fields, an X in the fifth, and uses Enter for the action key.
input. = ’
input.5 = ’X’
input.0 = 5
